Clinical Trial Summary

The aim of this study is to investigate the effects of Xanthohumol on resting energy expenditure and substrate oxidation in healthy women. It is assumed that resting energy expenditure and fatty acid oxidation is higher after Xanthohumol ingestion.

Description:

In a crossover design, 16 healthy young women ingest 172 mg micellar solubilized Xanthohumol or placebo in a randomized fashion. During an observational period of 3 hours, the acute effects of Xanthohumol on the resting energy expenditure and substrate oxidation is determined by respiratory gas analysis. An additional 30-minute determination of the resting energy expenditure and substrate oxidation is executed 24 hours after Xanthohumol ingestion. The wash-out period will be 28 days.
